Both you and Dan are assuming that I actually care about this hardware
and driver enough to read a presentation or watch a video about it.
Sorry, but that's not happening :)
I'm saying these questions as you all need to be asking yourself that,
and figuring out what the proper api is. That's not my job here. I was
just pointing out the problems in your original submission that you all
should have caught before sending it out...
good luck!
